Introduction
Under normal circumstances, postoperative axillary swelling after breast cancer surgery may be caused by lymph node removal, fat liquefaction, postoperative inflammatory response, hypertrophic scarring, lymphatic vessel injury, and other factors. If you experience any discomfort, it is recommended to seek medical attention promptly. In daily life, maintaining a healthy lifestyle, eating a light diet, engaging in moderate exercise, keeping the wound clean, and avoiding infection are advised.
Normally, axillary swelling after breast cancer surgery may be caused by lymph node removal, fat liquefaction, postoperative inflammatory reaction, scar hyperplasia, lymphatic vessel damage, and other reasons. If discomfort occurs, timely medical consultation is recommended. Detailed analysis is as follows:
1. Lymph Node Removal
During breast cancer surgery, axillary lymph node dissection is often involved. When lymph nodes are removed, the normal flow path of lymph fluid is interrupted, causing lymph fluid to accumulate near the surgical area and resulting in swelling. The use of compression sleeves and regular physical therapy, such as lymphatic drainage massage, may help alleviate the condition.
2. Fat Liquefaction
After surgery, fat tissue may liquefy due to ischemia, hypoxia, or other factors, leading to axillary swelling, which may also be accompanied by symptoms such as fever and fluctuation. Regular wound dressing changes under a doctor's guidance are necessary, along with maintaining wound dryness and cleanliness to prevent bacterial growth.
3. Postoperative Inflammatory Reaction
During the healing process of the surgical wound, the body produces an inflammatory response to remove dead tissue and promote repair, which may cause axillary swelling and may also be accompanied by pain. Under medical guidance, medications such as Cefadroxil Capsules, Amoxicillin Capsules, and Ibuprofen Sustained-release Tablets may be used for treatment.
4. Scar Hyperplasia
Individuals with a scar-prone constitution are more likely to develop scar hyperplasia during the healing of surgical wounds, leading to localized swelling in the axillary area, possibly accompanied by itching. It is recommended to follow medical advice and use medications such as Heparin Sodium Tablets, Halometasone Cream, and Rutoside Cream for treatment.
5. Lymphatic Vessel Damage
During breast cancer surgery, besides lymph node removal, lymphatic vessels may also be damaged, causing lymph fluid accumulation, resulting in axillary swelling, along with symptoms such as skin hardening and fibrosis. Mild exercise can help promote lymphatic fluid flow.
In daily life, maintaining a healthy lifestyle, eating a light diet, exercising moderately, and keeping the wound clean to prevent infection are recommended.
